Question

to evaluate the defect rate of its memory chips, an integrated circuit manufacturer tests every 100th chip off the production line. out of 10 chips tested, one chip is found to be defective. the manufacturer concludes that 3 chips out of 3,000 will be defective.

Answer 1

Step-by-step explanation:

Given to evaluate the defect rate of its memory chips, an integrated circuit manufacturer tests every 100th chip off the production line. out of 10 chips tested, one chip is found to be defective. the manufacturer concludes that 3 chips out of 3,000 will be defective.

• We need to find whether the conclusion is valid or invalid.
• So according to the question a person manufactures integrated circuits. In that circuit the memory chips are defective. So in order to find out the defect rate, the manufacturer tests every 100th chip off the production line.
• So one chip is found to be defective out of 10 chips tested. In the similar way if he goes on testing he can conclude that 3 chips out of 3000 chips will be defective.
• Therefore this is a systematic random sample and it is unbiased. The reason or conclusion is valid
